FLOOR CON STRUCTION.

Application led August i9, 1926. Serial No. 127,980.

This invention relates toan improved type of floor construction'.y more particularly adapted to commercial-installations in which a floor resistant to heat and proof against corrosion is essential or desirable.

A floorconstructed in accordance with thel present invention may be substantially iireproof, may be highly resistant to the e'ect of chemical deterioration due to acids l0 or the like and is adapted to endure considerable Wear -due to trucking, moving of heavy objects, etc. The present invention in its, more s ecific aspect relates to the formation of a oor by assembling a large number 'of strips of resistantiireproof material such as commonly used for roofing and siding; the strips preferably being of undulatory form with interiittlng undulations to hold them in proper engagement with each 9 other. For such a purpose a composition comprisin ,asbestos fiber which has been bound wit suitable hydraulic cement, compressed under high pressures, 'and weathered for a certain length of time.

Further objects and advantages of the 'invention will be apparent to 'those skilled in 'the art upon a reading of the subjoined description and claim in conjunction with the .accompanying drawings, in which:`

Referring to the accompanying drawingsand more particularly to Figs. 1 and 3 there- 40 of, a floor is constructed of stri s 1 of rsistantmaterial, preferably having an un-y dulatory yform,such for examplel as corru-l gated asbestos bound with adhesive material such as hydrauliccement.Strips 1 are preferabl cut to provide the floor with a considera le depth and have their Hat lower -edges disposed upon the conventional ioor beams or joists 2 with interitting corrugations or undulations 3 in mutual engagement 'I0 witheach other so that a substantially solid or continuous'layer of resistant flooring isl viously, if desired, t

provided. The ends of the aligned strips may be located either above the beams 2 as indicated by the numeral 3` (Fig. 1) or their abutting ends may be located between the the invent-ion particularly useful in installations where a draft passing 'through the floor is desirable asin dryers and the like. In this form of the invention the strips are spaced from each other to provide an open grid-like construction with overlap ing endsv of the strips forming spacers to efine the spaces therebetween as desi ated by numeral 6 (Fig. 2). Preferabyx7 these overlapping ends are located above the floor beams 2 which may; be of any form. Obe degree of spacing ma be varied to suit different conditions an when the span between adjoining ioor beams is comparatively wide, it may be desirable to introduce additional spacers 7, consisting of short lengths of corrugated material between the long strips which bridge the spans.

,Obviously floors of this type of constructionare formed particularly useful in commercial installations wherein floors of ordinary material do not have the desired qualities of endurance under the wear of heavy truckin moving of machinery and the like, especial y when also subjected to high temperatures or the corrosive action of strong chemicals.

`In any of its alternative forms, the stri s composingthe flooring herein described will reta-1n their positional relationship best when held tightly together, as by any marginal wedging devices which may be found convenient, and will, when soxheld compactly in mutual contact, require no further'or other holding means. l v

I claim:

A door 'comprising' beams and narrow comparatively deep strips of cement-bonded asbestos fiber spanning spaces therebetween,

vsaid .strips having longitudinally undulated m i Leeeee surfaces in mutually intertting engagetween beams, these strips being held in piace ment, the strips being so shaped that a. plane by the interlocking engagement, of their untangent to successive re-entrant areas upon dulated surfaces with similar surfaces of ad l0 one v sidev thereof will cut the surface `upon joining strips. w -v the opposite side between said re-entrnt Signed by me :1t-New York, N, Y., this 4th areas.l certain of the strips having their ends day of August, 1926, .Y Y
